Car batteries store and use the electrical energy that is used to start the vehicle's engine and power its electrical systems. The car battery must be reliable and match the different specifications of the vehicle. Replacing your car battery is necessary when the battery starts to age or stops working properly - a car battery has a lifespan of around 3-5 years, depending on usage conditions and maintenance. Low-cost car batteries are certainly a very attractive option, but it's worth remembering that battery quality is also important. Varta car batteries are renowned for their reliability and long life. Choosing a car battery will of course depend on the electrical needs of the car and the battery's specifications, capacity and cold-start current, for the specific vehicle.
